#65303 - Trigger is the correct word, she had an orgasm with a fierceness that I'd never seen grandma produce and I had to kiss mom hard to stop her making any loud noise that our neighbours might hear. I know Alice came in from the shower and sat watching her daughter be fucked by her stepson, and I know mom knew which seemed to make my lust even more intense. I won't expect to have sex with you when dad is around, but whenever he's away you're mine! Do you agree? My fingers were brushing across her erect nipples and then I cupped her magnificent breasts and nibbled gently on an erect nipple before laying her down onto her back on the sofa and beginning the 'grand tour' of my step-mother's body.
